On the modern plant's production line, a 24-position automatic tool changer accurately changes tools at a speed of 1.2 seconds, while the spindle maintains high-speed continuous operation at 12,000 rpm. All this is made possible by the machine's precise frame design, which underwent finite element analysis.

The main advantages of the DNM 4505 model are the axial travel of 800/450/510 mm, the table size of 1000x450 mm and the maximum load capacity of 600 kg.

This vertical machining center comes standard with a high-performance direct-drive spindle with a maximum speed of 12,000 rpm (optional), as well as roller linear guides. Acceleration of all axis feed systems is 50% higher than that of previous models.

Product overview

The Doosan DNM 4505 vertical machining center is a high-performance machine designed for modern manufacturing. Designed and manufactured by DN SOLUTIONS (formerly Doosan Machine Tools), this model incorporates cutting-edge design and control technologies.

This medium-sized model in the DNM series is suitable for efficient processing of various complex parts and is widely used in many industries such as aerospace, automobile, mold making and precision parts processing.

This machining center is designed to meet user needs for machining accuracy, production efficiency, and reliability. With its optimized design and advanced functionality, it provides users with a comprehensive material processing solution.

Analysis of design advantages

The Doosan DNM 4505 machine tool incorporates a number of advanced technologies to deliver superior performance in high-speed, high-precision machining.

Regarding the foundation design, the DNM 4505 model utilizes FEM (finite element method) technology to optimize the foundation structure. By adding stable support points and thickening and widening key elements without changing the overall volume, the foundation's stability and rigidity are significantly increased.

This design effectively reduces vibration during processing, laying the foundation for improved processing accuracy and surface quality.

The motion system is another distinctive feature of this machining center. All axes are equipped with roller linear guides and lubricated with environmentally friendly grease. Compared to traditional sliding or ball guides, roller linear guides offer significant advantages in load-bearing capacity and service life.

It is particularly noteworthy that the DNM 4505's axis feed rate is 50% higher than its predecessor, meaning the machine responds faster during rapid positioning and contouring, effectively reducing the machining cycle.

Advantages of the main component

The high-performance direct-drive spindle of the DNM 4505 machining centre offers outstanding performance in both design and operation.

The direct-drive design eliminates vibration and efficiency losses associated with traditional belt drives, and reduces acceleration and deceleration times by 70% compared to previous models. This improvement not only increases machining efficiency but also reduces stress on the cutting tool and workpiece.

To ensure spindle stability during long-term operation at high speeds, the DNM 4505 is equipped with a spindle oil cooling system as standard. Cooling oil circulates through the spindle bearings and integrated motor, minimizing thermal drift and ensuring high-precision cutting.

The tool magazine and tool change system were also designed with high efficiency in mind. The automatic tool change system (ATS) has been optimized, resulting in a significant increase in tool change speed. Specifically, the time between tool changes has been reduced by 20%, and the time between cuts by 14%.

The standard 24-tool magazine (optional 30 or 40 tool positions) allows multiple tools to be stored simultaneously, meeting the needs of multi-process machining of complex parts, avoiding frequent tool changes during machining and significantly saving production time.

Improve the after-sales service system.

Doosan Machine Tools has established a global customer service network to provide comprehensive after-sales support to DNM 4505 machine users.
